French Guiana (French: Guyane française, officially Guyane) is an overseas department (French: département d'outre-mer, or DOM) of France, located on the northern coast of South America. Like the other DOMs, French Guiana is also an overseas region of France, one of the 26 regions of France. As a part of France, French Guiana is part of the European Union's territory, and its currency is the euro. Though sharing cultural affinities with the French-speaking territories of the Caribbean, French Guiana cannot be considered to be part of that geographic region, with the Caribbean Sea actually being several hundred kilometres to the west, beyond the arc of the Lesser Antilles.Coastline: 378 kmClimate: tropical; hot, humid; little seasonal temperature variation
